How is the University cleaning and disinfecting buildings across campus?
Occupied Buildings: In addition to routine cleaning performed by the Custodial Department, ISU has implemented enhanced cleaning procedures. These procedures include increasing the frequency of cleaning and disinfecting commonly touched surfaces (door handles, railings, elevator buttons, bathroom stall doors). Some common areas, including computer labs and the Recreation Center, have specific cleaning protocols that are posted for those utilizing the space. All disinfection is performed utilizing EPA Registered Disinfectants.
Unoccupied Buildings: All unoccupied buildings from spring 2020 are receiving a one-time deep clean to coincide with employees returning as part of the Roaring Back: University Rebound Plan. This deep clean includes the use of a chemical fogging machine which delivers electrostatically charged particles to surfaces. The chemical particles adhere to surfaces and continue killing germs for 72-hours. Fogging cannot be performed in occupied areas. All disinfection is performed utilizing EPA Registered Disinfectants.
How can I disinfect my workspace?
Departments and Units should disinfect break rooms, shared appliances, remote controls, desks, phones, tools, equipment, lab equipment, computer mouses, keyboards, exam rooms and other commonly touched surfaces several times per day using an EPA Registered Disinfectant. It is important to protect sensitive equipment and hardware from chemical cleaning agents. All cleaning products should be used according to the manufacturer labels including wearing disposable gloves when directed. Excess cleaning chemicals should be evaluated for proper disposal by ISU Environmental Health and Safety. After disinfecting surfaces, wash hands thoroughly.
How will ISU clean and disinfect an area with confirmed COVID-19?
If possible, an area with a confirmed COVID-19 case will be closed off and left vacant for a minimum of 24 hours. If not possible, the doors and windows in the space will be opened for ventilation. Custodial staff will wipe down the entire space from top to bottom. After all surfaces are cleaned, the fogging machine will be used and the space will be locked with signage to notify the campus community that the space is being disinfected.
What is the difference between cleaning, disinfecting, and sanitizing?
According to the CDC, cleaning removes dirt, germs and impurities from a surface or item. Cleaning a surface or item does not necessarily kill germs. However, removing germs from a surface may lower their numbers and therefore the risk of spreading infection.
Disinfecting a surface or item involves the use of chemicals to kill germs. Disinfecting does not remove germs from a surface but when used in combination with cleaning, germs are both killed and removed from a surface or item.
Sanitizing reduces the number of germs on a surface or item to a safe level. This level is based on public health standards or requirements.
How should I disinfect a surface?
When disinfecting a surface, wear disposable gloves and eye protection if directed by the label. If the area being disinfected does not have good ventilation, leave the area until the surface has dried and fumes have dissipated. First, clean the surface with a paper towel, soap, and water to remove dirt and germs, then apply disinfect to a paper towel and wipe the surface. Ensure that the disinfectant is evenly distributed and stays wet for the recommended kill/contact time. After disinfecting, discard disposable gloves and clean hands immediately.
